Amazon. com has received a patent(专利) right to send its products to customers by drone planes. The company is the largest US-based online seller of products by mail and other services. Now, the company has received a patent for its planned drone delivery system.

In March, federal officials allowed Amazon to test its drone delivery plan. But even with a patent and the ability of drones to make deliveries, it does not appear the company will put its new delivery system in place any time soon.

The US Patent Office published the document, which describes Amazon’s plans to use GPS to deliver products to homes and to wherever people are. The drone will use a customer’s mobile device --- usually a smartphone ---to avoid hitting people or buildings and to find a secure area to land. The company wants to deliver products within 30 minutes after people order them on its website.

However, the Federal Aviation Administration (FAA) is worried about the safety. Although it allowed Amazon to test the system, the agency said the operators must be able to see the planes. That greatly limits the delivery area.

Loretta Alkalay is a professor at the Vaughn College of Aeronautics and Technology in New York. Although Amazon is not yet offering drone delivery, Professor Alkalay says it will not be long before it does. She says there are worries that the drones will hit buildings or people, or that the products and drones will be stolen or damaged by people on purpose. But she says that is because many people believe the drones would only deliver the products to the front door of a house. “However, it is possible that homes will one day have special area on their roofs designed to receive product deliveries,” she adds.

On behalf of the Obama family,I want to wish you a very happy Thanksgiving.

Like many of you. we'll spend the day with family and friends,catching up,eating some good food and watching a little football.Before we lift a fork,we lend a hand by going out in the community to serve some of our neighbors in need.And we give thanks for each other, and for all of God's blessings.We all share this day,united by the gratitude for the bounty(慷慨) of this nation.

And we welcome the contributions of all people-no matter their origin or color or beliefs-who call America home, and who enrich the life of our nation. It is a belief as old as our founding:“Epluribus unum” -- that out of many,we are one. We are reminded that this creed, and America itself was never an inevitability, but the result of ordinary people in every generation doing their part to uphold our founding ideals-by taking the blessings of freedom, and multiplying them for those who would follow.

As President Kennedy once wrote, even as we give thanks for all that we've inherited from those who came before us-“the decency(庄重,正派) of purpose, steadfastness(坚定)of resolve and strength of will, for the courage and the humility, which they possessed.” we must also remember that “the highest appreciation is not to utter words but to live by them.”

Today,we are grateful to all Americans who do their part to live by those ideals, including our brave men and women in uniform overseas and their families, who sacrifice so much to keep America safe.We are grateful to the countless Americans who serve their communities in soup kitchens and shelters,looking out for those who are less fortunate,and lifting up those who have fallen on hard times.

This generosity, this compassion, this belief that we are each other's keepers, is essential to who we are, not just on this day,but every day.It's easy to focus on what separates us.But as we gather with loved ones on this Thanksgiving, let's remember and be grateful for what ties us together.

Our love of country.Our commitment to justice and equality.Our belief that America's best days are ahead,and that her destiny is ours to shape-and that our inherited ideals must be the birthright of all of our children.

That's what today is all about: that out of many,we are one. Thank you, God bless you.

Who would have thought to put a kite and a surfboard together? It may seem like an impractical idea, but a man named Cory Roeseler from Oregon believed that it would work, and introduced the idea in the 1980s.1. Over the next few years, other designers contributed to the style and shape of the board, resulting in a mixture of kiting and surfing, which is what kite surfing is today.

2. The power kite pulls a small board that is fastened to the surfer’s feet, and there is a harness (安全带) that goes around the surfer’s waist to make sure that the surfer stays connected to the board.The wind determines which direction would be easiest for the surfer to go in.Once the kite surfer is able to control the board and the kite, they can learn many tricks, such as turning, jumping, and so on. 3.

This sport can sometimes be potentially dangerous to other kite surfers, beachgoers, and the kite surfers themselves if they don’t know how the proper procedure is done.4. They can learn the techniques safely without putting themselves and others in danger.A good course should include basic operations, kite set-up, maintenance (维修) of equipment, weather planning, and emergency landings.These courses are available in almost all areas where kite surfing is popular.

5. Some popular destinations for kite surfing enthusiasts are South America, Europe, Asia, Africa and Australia, but wherever there is wind, there will be kite surfers.You might even be able to see kite surfers on the beach closest you!

A.Kite surfing has become a mainstream sport.

B.Kite surfing is a difficult and dangerous sport.

C.The way it works is an application of simple physics.

D.The first design was with water skis powered by a kite.

E.It is also known as kite boarding, and in some European countries as fly surfing.

F.Therefore, it is highly recommended that people who want to participate in this sport attend a

course.

G.With the combination of the wind and the ocean, some kite surfers can go at top speeds while

flying over 20 feet in the air.

Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas. 1.

Most Americans would find it hard to imagine what life would look like without cars. 2. . The polluted air becomes poisonous and dangerous to health.

3. . That’s what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.

Another way is to take the place of the car engine by something else. 4. . Many makers believe that it will take years to develop a practical model that pleases man.

To prevent the world from being polluted by cars, we’ll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help the air clean. But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down. 5. .

Although cars have led us to a better life, they have also brought us new problems.

A.Inventors are now working on steam cars as well as electric cars

B. Americans know cars very well.

C. However, some have realized the serious problems of the air pollution that is caused by cars.

D. One way to get rid of the polluted air is to build a car that does not pollute.

E. However, the number of vehicles has continued to increase in recent years.

F. Americans won’t live without cars!

G. Thus the problem of air pollution would become less important than that of unemployment.
